Product Overview

The AD7224KNZ is a precision 8-bit voltage-output Digital-to-analog Converter with output amplifier and double buffered interface logic on a monolithic CMOS chip. No external trims are required to achieve full specified performance for the part. The double buffered interface logic consists of two 8-bit registers-an input register and a DAC register. Only the data held in the DAC registers determines the analog output of the converter. The double buffering allows simultaneous update in a system containing multiple AD7224. Both registers may be made transparent under control of three external lines, CS, WR and LDAC. With both registers transparent, the RESET line functions like a zero override, useful function for system calibration cycles. All logic inputs are TTL and CMOS (5V) level compatible and the control logic is speed compatible with most 8-bit microprocessors. Specified performance is guaranteed for input reference voltages from 2 to 12.5V when using dual supplies.
  • Low total unadjusted error - less than 1LSB over temperature
  • Extended temperature range operation
  • mP-compatible with double buffered inputs
